We present C 1s x-ray absorption, x-ray emission, and resonant inelastic x-ray scattering ͑RIXS͒ spectra of single-phase crystalline K 3 C 60 . The comparison to valence-band photoelectron spectra from the same sample facilitates identification of the contribution from surface and bulk electronic states in the latter. Bulk-sensitive techniques show that the valence bands of K 3 C 60 and pure C 60 are characterized by spectral features of similar width, in agreement with the predictions of band-structure calculations. Symmetry selectivity in the RIXS process allows us to assign peaks in the C 1s absorption spectrum, demonstrating a close correspondence with pure C 60 also in the conduction band. The symmetry selectivity is as pronounced in K 3 C 60 as in pure C 60 , indicating that the local C 60 symmetry is not appreciably affected by the K doping, either in the ground state or intermediate state, on the time scale of 6 fs.
